I have been searching the forum for flywheel tech, and have come up with this.
In a manual trans you want a heavy flywheel to prevent stalling when engaging clutch. But at the same time a heavier flywheel takes more energy to get up to speed. If you are going through 4 or 5 gears you are spinning that flywheel up to speed 4 or 5 times in a row and wasting a LOT of energy. I just did some research and found out the flywheel in my auto weighs 30 LBS!!!!! The aftermarket FW weighs in at a whopping 14.9 LBS!!! THATS HALF THE ENERGY TO GET IT MOVING. If i consider the fact that my car weighs just under 4,000 LBS i need to cut as much weight as possible. A lighter flywheel would also make starting a LOT easier, especially in winter. Oh, and then you have better throttle response too, and maybe quicker 0-speed limit times as well.

EDIT: Oh, and you would probably have less body roll in corners and less stress on engine mounts because a lighter flywheel would have less resistance to change of axis compared to a heavy beast.

I just think lighter FWs make sense on auto trans cars.

please let me know if i an wrong but please don't spout off if you have nothing to back it up.
